Platypus(Former Criptid)

The platypus was once considered to be a cryptid because it has the characteristics of a reptile, mammal, and bird. Platypuses ("platypi" and "platypodes" are also considered acceptable plural forms) were first encountered by Europeans in 1798. When British scientists were given the first specimen, they tried to remove the "duck's bill," thinking it was a fake sewn together by Chinese taxonomists. The same platypus now resides in a British museum, and the scissor marks are still visible on the bill.
